Specification of To all whom it m 1;1 cor/cm):

lie it known lhat I. Join: Barman, $12, a (-ilizcn of the United S'l'a'ics, residing al. lion Angcles, in the county of Los .flugeles and Slate of California, have invented certain new and useful ii'niprorczncnts in Shock-ii)- sorbcrs; and I do hereby declare the fr loving to be a full, clear, and exact description of the invcniion, such as will enable others skilled in the a re lo which it appertains to make and use t e same.

This in ention relal'es to she a tisorbcrs of the cylindc and piston type for use upon "ehicles and is designed more particularly for use in connection with automobiles.

One of the objects of ehe inven'lion res-h s in the provision of shock absorber of (his nature, which shall he of extremely simple construction, very cfilcicnl. and n "1h w" not interfere Wllll lhc cushioning n of he springs of a vehicle.

Another object of the invention is vide a device oi this nature which very effective in controlling the recs springs, since it is the return nioyeinent or vehicle body which mosi; disturbs the occupants and cause the greatest strain upon a vehicle.

Another and more specific she invcntiongesicies in the provision of a shock absorber or" the cylinder and piston type in which the piston head is of a peculiar construction so as to permit of the air or liquid within the cylinder flowing rapidly through said head when the valve is open.

, lVith these and other objects in view,

lion proceeds, the invention consisis certain novel features of construction, combination, and arrangementof parts, as will be hereinafter described and claimed.

For a complete understanding my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a longitudinal sectional View through my improved shock absorber, paris thereof being shown in elevation, and, Fig. 53 is a top plan View of ihe piston.

Referring in detail to the drawings by numerals, 5 designates a cylinder or dash closed at its upper end by the interformed wall or head 6 formed with a opening, 7 which closed by the screw plug 8, and at its lower end by a removable head letcezs Pa tent.

9 formed with the smiling box 10. A socket r slceve ll is formc: integrally upon the head 6 and receives a boll 12 which is allached to the vehicle frame l3, by means of a nut 14-. A locking screw 15 is threaded through the sleeve into cngagemcnl with the bolt 12.

A. piston rod 16 es lhrough the smiling box in which retained the packing" i? by Ines as of a packing gland 18. The lower end of the piston real is enlarged, as imii caied at a'ndlrc"versely apertnred to permit ihe passage of the bracket arm 20. This 1 rm is holied lo the springs 21 and cara pin which prevents the piston rod becoming disengaged.

A peculiarly constructed piston head, gen orally :Lsiggnaced 23, is secured to the rea spider formed by lhe 'nwardiy and onhvardly "a, and an annular llill spider arms. The sleeve surrounds the reduced portion 2 of the piston rod and is c,

secured thereto by the pin 28. The arms here shown as four in number, extend from the periphery of the sleeve adjacent its up per end and are secured to the horizontal wall 29 arid the verlzical Wall 27 of thenngle iron rim. A circular strip of packing 81 is secured to the riml? by means of the ring and screw bolts 3 ihe latter passing; through the Wall 29 or e rim and thread ing into the locking rir oil. A disk val having the relative small ports 36, is slidable upon the piston rod 15, and is for the purpose of controlling the flow of liquid I through the skeleton piston head. A pin 37 extends through the piston rod below the valve and limils the' downward movement of the latter butper nits it so drop away from engagement with the rim of the piston.

Having described the consiruction of my shock absorber, I will now explain its operae l inhereil. e' n m it zill'eelesl lay the '1 so the i2 clre he (l 9 of the {3 went (:onl'rol,

while I. have .zrerl emhedierslmual tl':

Having thus described my invention, whet l claim 1531 In a deuce oi the character descrlbed, a

cylinder, a piston rod, :1 plsten heed secured lo 5:11 (l rod and comprising a. sleeve sur rounding the rod, a plurality of 21111155 inelined to said sleeve, and a rim formed upon the outer end of the arms, said rim being of angle iron construction having one all engaging the inner surface of the cylinder and lying in. a plane parallel to the heads of the cylinder, and a second wall spaced from the inner surface of the cylinder, :1 disk valve slirlehle upon the piston rod, means for lnnltmg the movement of the valve eway frem said piston head, the valve bemg adapted tosent against the second mentioned well. of the piston rim and being formed wi a, plurality of restricted ports.

In testimony whereof I affix my signature in presence of two Witnesses.
